June 27, 2011 – Hugues Duval broke his own world speed record for an electric aircraft, flying his electric Cri-Cri MC15E E-Cristaline to a speed of 152.7 knots (262 kph) at the Paris Air Show on Saturday, June 25. Duval’s previous record - also in E-Cristaline - was 141 knots, set in September 2010 at the Pontoise (France) Air Show. Saturday’s record speed was verified by the Aero Club of France and must be approved by the Fédération Aéronautique Internationale (FAI) to become official.

Generally considered the world’s smallest twin-engine airplane, the Cri-Cri E-Cristaline is powered by two 25-hp Electravia electric motors getting their go-juice from a pair of lithium-polymer Kokam batteries, turning two E-PROPS propellers. Electravia claims a 46 percent drag reduction over conventional powerplants thanks to extensive aerodynamic work on the fairings and equating to a 30 percent speed increase.

In April this year, E-Cristaline was one of three finalists for the Lindbergh Electric Aircraft Prize (LEAP) “Best Electric Airplane” award, which went to the Pipistrel Taurus Electro. The other finalist was the Sunseeker II solar airplane.
